摘要
在推导声相关声呐计程仪原理的基础上,建立了声相关声呐计程仪接收信号的自功率谱和相关函数的数学模型,详细分析了声相关声呐计程仪的各种测速误差。
According to the principles of the acoustical correlation log which was given, the power
spectrum of a received signal and mathematical model of correlation function about the acousti
cal correlation log were built and all kinds of errors of the acoustical correlation log were de
tailed in this paper.
